RECORDING LOCK.

Application filed October 23, 1919. Serial No. 332,643.

This invention relates to recording locks the object being to provide a lock for a door or other movable parts whereby the time of looking or unlocking the door or other part is recorded. The principal object of this invention is to provide a recording lock of simple and inexpensive construction having a minimum of movable parts, the construction being of a character whereby the operation of a key to lock the door produces a record on a strip of paper giving the time of looking and unlocking whether ante-meridian or post-meridian and further giving an indication of the key utilized whereby the clerk locking or unlocking the door may be known. A further object of the invention is to provide a mechanism for the general purposes described including a tape or strip for receiving an impression from members operated by the key in turning the \lock to locking or unlocking position and in so operating the key to move the strip to bring the blank portion thereof in position to receive the impression. A further object is to provide an impression device of a character to produce an impressionon the strip by rotation of the key in one direction movement of the key to rotation in the other direction no't resulting in operation of the said impression device.

These general features and other objects and novel features of the construction are hereinafter more fully described and claimed and shown in the accompanying drawing in which a I I F ig. 1 is a plan view of a recording lock embodying my invention showing the dial by means of which the time impression is produced. a d

This recording lock device is of a character adapted to be' applied to a door or other movable object desired to be locked in relation to a fixed part and it consists of an ordinary lock case 1 supported in the door or movable part 2 and provided with a lock bolt 3 that may be projected or withdrawn to lock or unlock the door. Mounted upon the door on the inside is a base 4 and mounted upon this base is an enclosing case 5 preferably adapted to be detachably supported to the base or hinged thereto as may be convenient and whereby the recording mechanism mounted upon the base may be exposed to view for adjustment or repair. This base member 4 has an outwardly extending portion 6 at the bottom forming the bottom of the case 5 and providing a support for the clock device indicated at 7 supported on this portion 6 by means of brackets 8 on each side. ,Mounted on the vertical portion 4 of the base is a rubber impression block or platen 9, beneath which runs strips of'paper 10 from theroll 11 su ported on the spindle carried bythe base. eneath. the platen 9 as will be understood from Fig. 4 is a series of impression devices'l3, 1-4, 15 16 87 in the bracket 34.

and 17 vertically reeiprocable in a supporting bar or arm 18 mounted on the base member 4. An impression or ink ribbon 25, similar to a typewriter ribbon, is mounted on pins 19 and 20 carried on the base 4 running from the pin 19 over the roller 21 to a roller 22 passing beneath the impression block or platen and thence downward to the roller 20. These rollers 19 and 20 are provided with coiled springs 23 and 24 at the outer end whereby the rollers are yieldably held from rotation and the ribbon held taut and in the present mechanism, as shown in the drawings, the ribbon is moved through rotation of one or the other of the rolls by hand whenever it is found necessary. The

impression strip 10 is carried from the roll 11 beneath the block or platen 9 above the horizontal part of the ribbon 25. The strip extends from the block 9 over a bar 26 which tends to hold the strip in contact with the impression block or platen 9 and a spring projected member 27 is provided engaging the strip above the bar 26 and preventing a looseness of the strip about the block or platen 9. This member 27 is downwardly projected by means of a spring 28 on the plunger member 29 supported in the block 30 carried on the base member 4. It is to be noted that the roller on which is mounted the roll 11 of the strip has a spring 31 at the end thereof tending to yieldingly hold the roll 11 from rotationf Thus, as the strip is drawn from the roll it is held taut between the roll and bar 26 and 27.

The key to be utilized with this lock may be of any approved type and of a length to extend through the face of the lock 32 on the exterior of the door and extending through the lock case 1 and beneath the impression members 13 to 17 as shown in Fig. 4 and terminating in a rotatable block 33 supported on a bracket 34 mounted at the end of the arm 18 in which the impression bars or members are reciprocably mounted. As shown in Fig. 2, this block 33 has a slot 35 provided therein into which the end of the key projects and whereby rotation of the key turns the block on its pivot. In View of the pin 87 being eccentric to the center of rotation of the key I have provided a slot This slot has the form of an arc of a circle whose center is the center of rotation of the key and permitting the member 33 to turn on the center of rotation of the key. The pivot pin 87 is secured in the member 33 and rides in the slot 87". Pivotally mounted to the block at a point 36 at one side of the pivot point 35 of the block is a bar 37 pivotally connected at the opposite end to the lower end of a. pivoted arm 38. This arm 38 is pivoted at 39 to the'upper end of the bar 40 which is pivotally mounted at the lower end on a pin 41 to which is secured a coiled spring 42 tending to yieldingly hold the bar 40 from turning. The lever 38 is L-shaped in form having a horizontal portion 43 as shown in Fig. 1 extending over the strip 10 which extends beneath this bar 43 and above the end of the lever 40. The pivot point 39 of the lever 38 is so positioned that when turned to position shown in Fig. 3 the paper strip is bound between the part 43 of the lever and the upperend of the member 40 which is of a width equal to the width of the strip. Upon the lever 38 assumingthe binding position (which is about the position shown in Fig. 2), by rotation of the part 33 the member 40 and lever are moved outward to position shown in Fig. 3 drawing the strip from the roll and beneath the impression block 9. It is to be understood and noted that this is the first movement of the key, but, as the key is continued to be turned in the direction shown by the arrow in Fig. 3 and in Figs. 6, 7, and 8, the edge of the key at the finish of its movement as will be understood from Fig. 8, raises certain of the impression devices. With the character of key shown in Fig. 4 the impression device 13, 16 and 17 are raised and the impression devices 14 and 15 are not so raised due to the fact that the key has a notch 51 preventing the contact of the key with the said devices 14 and 15. In the case illustrated the impression device 13 is the device giving the impression of the key used which is indicated at 52 in Fig. 13 and this impression member 13 will always be raised to produce an impression through the ribbon on the paper strip each time the key is rotated in a direction to project or withdraw the latch bolt. Obviously the rotation of the member 33 in a direction opposite to that shown by the arrow in Fig. 3 after its completion of movement in projecting the bolt, will withdraw the bolt and actuate the members 38 and 40 in the identical manner above described and on completion of this latter movement will assume the position shown in Fig. 2. Other keys would be notched to prevent actuation of the member 13 and to actuate the member 14 or 15, there being a key for each of the impression members 13 to 15, respectively. It is to be understood that one side only of the key is adapted to engage or operate the impression device, the back edge, upon rotation of the key, not coming in contact therewith. Each person carrying a key is thus in locking or unlocking the door made to produce a corresponding impression on the paper strip and any number of impression devices similar to the device 13, but each of a character to produce different impressions may be employed depending upon the number of keys in use for the lock. It will be readily understood that the key passes through the member 32, lock case 1 and (although not here shown) it may be shaped between the notch 51 and outer end of the key to engage the latch bolt in the usual manner and that rotation of the key in one direction projects the bolt while rotation in the other direction withdraws the bolt and as it is essential to know when the door or other member is unlocked as well as to know when it is locked, I have provided an impression member 16 shown in Figs. 9 and 10 that is operable to produce an impression upon rotation in one direction only of the key. This device 16 is reciprocable in a slot 54 in the bar 18 which is somewhat wider at the bottom than the said member 16. This member 16 is L shaped having an oppositely projected end 55 at the bottom and rotation of the key 50 in the direction of the arrow shown in Fig. 9 simply moves the impression device to the position shown in dotted lines in said figure, the width of the slot 5 1 permitting such movement and allowing the key to turn without raising the member 16. Rotation in the opposite direction, however, as indicated by the arrow in Fig. 10 results in the key engaging the part 55 and, due to the slot having a perpendicular wall 56 on the right hand side, the said member 16 may not be turned to the right beyond a certain point and thus the impression may be produced on the paper indicating that the device is locked. T hus, if the tape bears an impression as indicated at 57 in Fig. 13, the large bolt is projected at that time while the absence of such impression as is shown by the right hand end of the drawing in Fig. 13 indicates that the movement of the key was to unlock the device at that time. In the case illustrated in Fig. 13 which was an impression produced by a locking and unlocking operation, the same key has been utilized because both key impressions 52 are the same in character. If another key had been utilized some other impression number 14 and 15 would have produced an indication on the tape.

As above stated the key is turned in one direction to project the lock bolt and in the opposite direction to withdraw the same. For this purpose the key is cut away on the back edge as indicated at 50 Fig. 4, but it is to be understood that any means may be. employed to secure this result as for instance mounting the barrel for the key in such manner that the center of rotation of the key is near the back edge. In operation the key is turned from its fiatwise entering position to about vertical position engaging the impression devices and releasing the lock arms 71 and 72 at the timethe lock bolt is actuated. The key is therefore turned through an arc of 180 degrees, and it is to be understood that the lock is of a type to permit withdrawal and insertion of the key with the notch 51 either to the right or left of the impression members.

It is also essential in a device of this kind to indicate the time when the door was locked or unlocked and whether it was in the day time or nighttime. For this purpose I have provided a dial 60 having aseries of numbers from 1 to 12 in Arabic notation on one side and occupying one-half the dial adjacent the periphery and on the other side a series of numbers from 1 to 12 in Roman notation. This dial is carried on a shaft 61 mounted in the clock case 7 and mounted on this shaft is a gear 62 meshing with a gear 63 attached to the usual hour hand shaft which projects from the case 7. It is to be understood that this shaft 61 is movable vertically through the hub of its gear 62 or the gear may be wide in face permitting movement in a vertical direction or limited distance without it being moved out of mesh with the operating gear 63. The dial is thus rotated continuously in accord with the passing of time and as will be noticed in Fig. 1 for instance the dial 60 has an edge thereof extending beneath the paper and impression ribbon and the numbers thereon together with the division marks between each'of the numbers are raised above the face of the dial so that when the dial is pressed upward against the ribbon and against the impression block 9 an impression is made on the paper somewhat after that as indicated at 65 and 66 in Fig. 13. The dial is raised through operation of the impression member 17 shown in perspective in Fig. 11 which has an offset portion 171 extending beneath the edge of the dial as will be understood from Fig. 4. This number 17 also has an arrow or diamond point impression member 172 on the upper face thereof adjacent the periphery of the dial when in assembled position therewith so that as the member 17 is raised by rotation of the key (and all keys are of a type to operate this member 17), the arrow or diamond point 172 produces an impression on the tape pointing directly toward the impression by the raised numbers and division marks produced by the dial as will be understood from Fig. 13. The division marks may be of any number desired as for instance the marks may be spaced to indicate one-sixth of an hour or ten minutes. Thus, with the arrow head or diamond point impression as shown in Fig. 13, the device was locked at 8 :15 and was unlocked at about 5. If the Arabic notation is utilized to indicate night time the door was locked at 8:15 in the evening and was opened at 5 in the morning.

As will be noted in Figs. 5, 15, 16, and 17, the bolt 3 is provided with two pairs of notches 69 and 70. Engaging in these notches are two arms 71 and 72, the arm 71 being secured to the extending end of the carrier member 12 and extending over the protruding lower edges of the impression devices 13, 14, and 15 and through the slots 74 and 75 in the base member 1 as shown in F igs. 5,15, 16, and 17. This member 12 is reciprocable' in the bar 18 and serves as aguide and support for the member 71 and all the keys are so made as to engage the lower end of this member 12 and the desired impression devices including one of the de vices 13, 14 or 15 to indicate the operator. As is shown more particularly in Fig. 17, the arm 72 is secured to the impression device 17 and engages in one of the pair of notches 69. IVhen these arms are in the position shown in Figs.1'5 and 17, the door is unlocked and to operate the bolt to lock the door, the key must be inserted its full length which upon rotation lifts the impression devices 12, 13, 14, 15, and 17 thereby raising the arms 71 and 72 out of the notches 69 and allowing movement of the locking bolt 8 to the locked position whereupon the arms 71 and 72 drop into the companion notches in the bolt 3 thereby holding the bolt in locked position. The object of this device is to prevent a person from cutting 01f the end of the key which actuates the recording device and thereby actuating the look only. With this device, it is necessary to use the full length of the key thereby operating the recording device before the lock can be locked or unlocked.

The paper strip as it is drawn from the roll 11 may simply'extend downward into the case or if preferred it may extend outwardly through a slot 75 in the case where each day it may be torn off and a record kept of the operations of the lock. By the construction described the tape or paper strip is held taut against the impression block or platen 9, and the impression ribbon 25 is held taut across the upper ends of the impression devices adjacent the face of the paper and at each operation of the key the strip is pulled forward whether the key is rotated in one direction or the other previous to operation of the impression device so that a blank portion of the paper is brought to position to receive an impression which is produced at the completion of rotation of a key either in looking or unlocking the device. It is further evident that the device is simple in construction and operation and by the arrangement of parts as described the impressions produced indicate what key operated the lock; wether the look was operated during the day or the night; whether the operation was such as to lock or to unlock the device, and the time of the -day or night when the operation was made, all of which is accomplished simply by insertion and rotation of the key without thought on the part of the operator.
